Tap the tempo
MainStage includes a “tap tempo” feature that allows you to set the tempo in real time while you
perform.
Tap the tempo on your computer keyboard
m Press Control-T several times at the desired tempo.
You can also tap the tempo using a screen control mapped to the Tap Tempo action. For
information about mapping screen controls to actions, see Map screen controls to actions on
page 71.
Get the tempo from MIDI Input
You can also have MainStage receive tempo changes from incoming MIDI messages. When the
“Get tempo from MIDI input” checkbox is selected, MainStage listens to incoming MIDI clock
messages for tempo information. If it receives tempo information, the concert tempo changes to
the new tempo value.
Get the tempo from incoming MIDI clock messages
1 In the Concert Inspector, select the “Get tempo from MIDI input” checkbox.
2 Choose the MIDI clock source from the Device pop-up menu.
When the “Get tempo from MIDI input” checkbox is selected, the Tempo slider is dimmed and
cannot be edited. If MIDI messages MainStage receives do not include MIDI clock information,
MainStage uses the concert tempo setting and changes the tempo when you select a patch or
a set with its own tempo setting or tap a new tempo. If MainStage stops receiving MIDI clock
messages, it continues to use the last received value for the tempo until you select a patch or set
with its own tempo setting or tap a new tempo.
